UNIVERSAL JOINT.

T all whom it may concern :j

Be it known that we',

ZwEIBnL, citizens of the United States, and residents of Wilkes-Barre,y county of Luzerne, State of Pennsylvania, have invented certain new and useful Improveof which the following is a specification.

rlhe present invention relates to improvements in ball and socket pipe joints and is particularly adapted for use as a connection between train pipes, especially the connection between av locomotive andits tender:

The object of the inventionfis'to provide a simple and durable construction includf ing a packing that can be compressed to XSS eiectually prevent leakage and provide a smooth yielding contact surface for the ball, thus avoiding the clamping of the ball between rigid surfaces.

An embodiment of the invention is illustrated in the accompanying drawing, in which: a

Figure l lis a longitudinal section through a joint constructed in accordance with the invention; Fig. 2 is an elevation.v

Referring to the drawing, the improved 'joint comprises a socket member or easing as having at one end an interior thread a `by means of which it may be secured upon a suitable pipe and a ball B having an exteriorly threaded extension b for en agement with a pipe. A soft metal rin is fitted in a suitable seat formed wit in the socket member A, said ring having a tapered section c which surrounds the ball B and forms a yielding abutment'therefor. Within the chamber or space formed between the socket A, ball B, ring C and a land D is arranged a packing E composed lof flake metal, graphite and asbestos fiber. The gland D is adapted to be adjusted to compress the packing E by means of a nut G screwed upon the casing A and having a lip g which bear's against the outer face of the gland. Means are provided for locking the ring G andI gland i-n any desired position.

As shown, the casing A is provided with an annular series of depressions or grooves a with which is adapted to engage a pin H mounted in a suitable guide-Gif G. The pin H is shown'a's'provided with a slot h through which extends a pin lf riveted at its ends to the guide G and acting to prevent the pin from being entirely with- A, shown Specification of Letters-Patent.

drawn from said guid'e. The pin may be secu-red in its locking position, as shown, by means of a suitable Cotter pin or key adapted to be passed through alined apertures in the guide G and the slot h. By withdrawing the cotter K the pin H may be moved radially of the ring G out of engagement with the depressions or grooves a andthe ring or nut can then be turned, by a suitable Spanner, to edect further compression of the packing E if necessary.

lt will be seen that the ring C and gland D, by their contact with the outer surface of the ball B, positively prevent waste or escape of any of the packing E and the latter, as described, is ofy such nature that it can be easily renewed if it becomes worn by adjusting the gland, as above described.

An important feature of the invention is thatV the compression cf the packing E is effected and the joint maintainedin proper fluid-tight condition without clamping the ball against any rigid or unyielding surface. lf after long use the soft metal ring C becomes undesirably worn, it can be readily removed and replaced. The particular packing which is employed in this joint is capable of being compressed suiiiciently to prevent leakage of fluid under pressure and possesses enough internal resistance to cornpression to withstand the pull and thrust that such a joint is subjected to and, as pointed out. if necessarv. further compression thereof is readily eiected.

Having thus described the invention what is claimed and desired to be secured by Letters Patent is:

l. The herein described pipe joint comprising a casing or socket member, a ball member positioned within the socket memmeans' for locking the nut in any adjusted position;

2. The herein described pipe joint comprising a an annular series of recesses in its outer surface, a ball member positioned within the casing or socket member havinguw comme iiiciuuel alla CORSI/1131115.-
